Application tiled April 19t 1907. Serial No. 369,088'- To all who/m. it fin/ary concern.'

Be it known that l, ALBERT L. SunARs, citizen of the United States, residing :it Soottle, in the county olf King ndv State oit iiliisln ing'ton, have invented now and useful lm- ]iiroif'omcnts in. ,Detachable Pipe-Couplings, oi' which the 'following is o specification.

My invontion pertains to detachable couplings for hose, pipo and. the like;y :uid it hos :l'or :its object to provide :i coupling which will permit of two Sections oi" hose or pipe hcinpr expeditiously connected togethor, mid this in such manner that .therc is no lizrhility ol' tho sections lining casually discoimcctod, und while tho soctions moy ho readily discon nccted at the ploosurc of tho porty using thc o0upli11g,yot leakage hctwoon tho momhcrs of' the coupling, when the sonic orc proporly intorlockod is :thsolutcly procludod.

With tho foregoing in mind` tho invcntion will bo fully understood from tho followingl description und chi-im when thc sanno orc rood in connection with thc. occompzuiyingr drawings, lorminp' port ol) tho slwci'licutiou, in whichm FiguroI l is :i sidol olcvittion illustrating my novol couplingr :is propcrly couuoctinu; two soctions ol' hoso.

l the saidspring catch will be placed under i tension. Then when the member B is turned there is noliability of the members being ber C. In turning theinember Btoward the 'the gasket H and said gasket will be c`om ber C is exteriorly ta ered toward its forthrou h a part of a revolution and the, lugs are placed back of the lugs F, the spring catch E will reach a position opposite i one of the recesses G and will spring outl Ward into the said recess. With the spring i catch E in this position, relative to the niember C it will be observed that the members i B andC-are strongly held against turning l with respect to each other, and consequently l casually disconnected. When, however, it is desired to disconnect the members, the operator has but to press the catch E inward i with his thumb so as to enable the said catch to clear the recess G, and then turn the meinber B backward or toward the left through a part of a revolution or until the lugs l) are clear of the lugs F when he may readily withdraw the member B .eiidwise from the meinright in making the coupling, it will be observed that by virtue of the tapered rear sides of the lugs D being opposed to the tapered rear sides of the lugs F, the forward end of the member B will be crowded against pressed, with the result that the connection will be rendered perfectly water-tight.

By reference to Fig. 2 it will be observed that the central `tubular portion g of the inein- Ward end, as indicate by m, and that portion of the member B in which said portion g is snugly received is corres iondingly taered, as indicated by 11,. *rom this it ollows that when the coupling is made, the portion g of member C is wedged in the member B, so that the connection between the members is water-tight even 'when the gasket H is deteriorated.

When desirable the peripheral portion f of the female member C may be threaded on the body ortion k of the member, this iii order to acilitate the manufacture ol' the member.

It will be gathered'froin the foregoing that my couplingis simple and compact in construction, and yet through the medium of the same two sections of hose or pipe may be svincoli expeditiously and easily connected andas readily disconnected, and this without liability of leakage when the coupling is madein order to impart a definite understanding f of said embodiment, but I do not desire to be understood confining myself to the said specilic construction and relative airangenient oi parts as such changes or modifications inay be made in practice as fairly fall within the scope ol my invention as claimed.

Having described my invention, what I claim and desire to secure by LettersPatent,

In a detachable coupling, a male member comprising a tubular portion having an interior abutment, and also having a rearwardly tapered bore extending to said abutment, dianietrieally opposite lugs extending circumierentially on the outer side ol the tubular portion and tapered at their rear sides in a common direction, and a longitudinally disposed spring strip connected to the tubular liortion and extending outward and 'forward lrom the point ol connectioiiand provided with an apex and terminating in a forwardly and inwardly inclinediieey end portion, in combination with a -female` member comprising a peripheral portion, lugs arranged at the inner' side of thel peripheral portion and having inclined rear sides, recesses formed in the inner side ol the peripheral portion iininedi ately adjacentto the smaller ends of the lugs, a central tubular portion extending beyond the peripheral portion and exteriorly tapered toward its forward end to snugly occupy the rearwardly tapered bore of the first mentioned member, and a gasket arranged iii the V'peripheral portion and surrounding the central tubular portion at the rear of tlielatter.

ln testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
